B.    Install ADOMD.NET.
C.    Run the Data Quality Server Installer.
D.    Make the data available for DQS operations.

You are the data steward for a Business Intelligence project.
You must identify duplicate rows stored in a SQL Server table and output discoveries to a CSV file.
A Data Quality Services (DQS) knowledge base has been created to support this project.
You need to produce the CSV file with the least amount of development effort.

Answer: C

You are implementing the indexing strategy for a fact table in a data warehouse.
The fact table is named Quotes.
The table has no indexes and consists of seven columns:
– [ID]
– [QuoteDate]
– [Open]
– [Close]
– [High]
– [Low]
– [Volume]
Each of the following queries must be able to use a columnstore index:
– SELECT AVG ([Close]) AS [AverageClose] FROM Quotes WHERE [QuoteDate] BETWEEN ‘20100101’ AND ‘20101231’.
– SELECT AVG([High] – [Low]) AS [AverageRange] FROM Quotes WHERE [QuoteDate] BETWEEN ‘20100101’ AND
– SELECT SUM([Volume]) AS [SumVolume] FROM Quotes WHERE [QuoteDate] BETWEEN ‘20100101’ AND ‘20101231’.
You need to ensure that the indexing strategy meets the requirements.
The strategy must also minimize the number and size of the indexes.
What should you do?

A.    Create one columnstore index that contains [ID], [Close], [High], [Low], [Volume],
and [QuoteDate].
B.    Create three coiumnstore indexes:
One containing [QuoteDate] and [Close]
One containing [QuoteDate], [High], and [Low]
One containing [QuoteDate] and [Volume]
C.    Create one columnstore index that contains [QuoteDate], [Close], [High], [Low], and [Volume].
D.    Create two columnstore indexes:
One containing [ID], [QuoteDate], [Volume], and [Close]
One containing [ID], [QuoteDate], [High], and [Low]

Answer: C

You are designing a data warehouse with two fact tables.
The first table contains sales per month and the second table contains orders per day.
Referential integrity must be enforced declaratively.
You need to design a solution that can join a single time dimension to both fact tables.
What should you do?

A.    Join the two fact tables.
B.    Merge the fact tables.
C.    Create a time dimension that can join to both fact tables at their respective granularity.
D.    Create a surrogate key for the time dimension.

Answer: D
With dimensionally modeled star schemas or snowflake schemas, decision support queries follow a typical pattern: the query selects several measures of interest from the fact table, joins the fact rows with one or several dimensions along the surrogate keys, places filter predicates on the business columns of the dimension tables, groups by one or several business columns, and aggregates the measures retrieved from the fact table over a period of time.
The following demonstrates this pattern, which is also sometimes referred to as a star join query:
– select ProductAlternateKey,
– CalendarYear,sum(SalesAmount)
– from FactInternetSales Fact
– join DimTime
– on Fact.OrderDateKey = TimeKey
– join DimProduct
– on DimProduct.ProductKey =
– Fact.ProductKey
– where CalendarYear between 2003 and 2004
– and ProductAlternateKey like ‘BK%’
– group by ProductAlternateKey,CalendarYear

You develop three Microsoft SQL Server 2012 databases named Database1, Database2, and Database3.
You have permissions on both Database1 and Database2.
You plan to write and deploy a stored procedure named dbo.usp_InsertEvent in Database3. dbo.usp_InsertEvent must execute other stored procedures in the other databases.
You need to ensure that callers that do not have permissions on Database1 or Database2 can execute the stored procedure.
Which Transact-SQL statement should you use?

A.    USE Database2
C.    USE Database1

Answer: B
